To ar/ZZ whom it 'um concern;

Beit known that I, BENJAMiN F. SHAKES- PEARE, a citizen ofthe United States, residing at the city ot' Chester, inthe count-y of Dela- Ware and State ot' Pennsylvania, have invented, certain new and useful Improvements in the'Method of and Apparatus for RefrigeratingParafne `and other Oils, olf' which the following' is a full, clear, and exact descrip- Io tion, reference being had tothe accompanying drawings. y

The general nature andpurpose of this invention are indicated by its title. Its object, specifically, is to provide an improved means .for securing in an economical manner the continuous and rapid congelation or refrigeration of thenoil (or distillate) in the manufacture of parat-'fina `although it is applicable in conuectionwith other oils whose temperature 2o it may loe/desiredV to quickly reduce.; Such oils being bad conductors of heat, there is required, under ordinary conditions and with the means and devices heretofore in vogue or known to me, 'a comparatively long time to sufficiently chill them. Iaccomplish the object stated by bringing together, by 'means of a'suitable apparatus, the warm oil and a refrigerating iluid-usually-brine brought artiiicially to a lo'w temperature-while iinely di- 3o vide'd and in, motion, or more or less in the form of.. spray.

I shall now proceed to describe an organized apparatus and the modas operandi which I have designed to eiiect this purpose, refer- 3 5 ence being had to the accompanying drawings,

0f which` Figure 1 is a side elevation, partly in section, of such apparatus; and Fig. 2is aview,

looking from beneath, of the system of oil and 4o coldwater-spraying pipes locate-(Lover the relceiver, D, Fig. 1, placed for the reception of the falling water and( congealed oil. ,il l

A is the tank, contained. O is a pipe hiving a series ot' laterally-projecting o, extending horizontally over a receiver, D. These lateral pipes are closed at their free en ds, but are pierced with a number ot' small orifices, x, Fig. 2, on their lower'sides, through 5o which the oil iiowing from the tank A escapes in numerous .streamlets iiLwhich the heat-eil `oil is leading therefrom, andpipes,

XV is a cold water or brinesul'iply pipe counecting with a 'three-pump, I), and extending alongside, and in the present instance below,

posite rows 0l streamlets are caused to biseet' each other, and also 4those ilowing from the oil-pipes, asillustrated in Fig. l. The streams oilV cold water and ol" warm oil becoming thus broken up by the force of gether, and a large surface of the refrigerating tluid being thus brought into close contact with the globules oi oil, it is obvious that the latterwvill quickly chill and the solidiiied paraiiine fall in small granules, q, with the Water into the receiving-tank D, the paraiiine iioating on top ofthe water, all as seen ini Fig. l. The water or brine escapes through openings Z in the bottom oi' receiver D into a` receptacle, F, wherein it may again be reduced in temperature by any suit-able means ybefore iii'iding its way into the wells I-I and I through the pipes lJ and 1,i'ioni which Wells it is pumped back by pump I) through pipe W, and soon indefinitely.

It is usually preferred to hav-e two wells or cisterns, so that they may be pumped from alternately. W'hile the water which has ac quired heat from the warm oil, in the act of relrigerating the latter, as hereinbefore described, is .ilowing into one of the said Wells, the pump is taking water previously allowed to iiow into the other well from the same source, and which has been. permitted to cool or has been artificially cooled in the latter. This maybe .regulated by means ol' stop-cocks S in pipe J delivering into the first well H, and in pipe K, leading into the second Well I, together with cocks `S in pipes M and N, connecting the force-pump and the wellsH and I, respectively. p

I am aware of the iact that oily liquids have been congealed by allowing the same to fall from one vesselinto another containing icethcir impact to-` IOO- water in numerous small streams, instead of in a single large stream, as customary. I do not, therefore, elaim that as being covered by my present invention.

Having thus described my invention, I elai m as new and usef'ul and desire to secure by Letters Patent- 1. The improved method or process of producing the congelation or cooling of paraliine and other oils, which consists in bringing together the oil and a refrigerating` liquid, both in a spray or comminuted condition, substantially as and for the purpose set forth.

2. The improved method or process of rap idly reducing the temperature of oils, which consists in forcing against a small body or bodies of oil in motion a series of slreamlets ot'a refrigerating fluid, whereby the said i'luids are caused to be broken up into small parti cles, or into a spray, substantially as and for the purposes set forth.

`3. An apparatus for congealing parafiinc and other oils, consisting ofthe following` ele ments, combined, constructed, and operating substantially as and for the purposes set forth, viz: An oil-supply pipe or pipes having a series of small orifices therein, a cold-watersupply pipe or pi pes,also with a series of small I orifices therein, the said oil and water pipes other oils, the combination of a system of oil supply pipes provided with series of small oritices,l and 4cold-\vate1;supply pipes with lll l if pipes and cold-water pipes, thel perforations ofthe said pipes being combined and arranged with relation to each other as shown and described, whereby the opposite streams of water are caused to biseet each other, and also the intermediate streams of oil, together with means for forcibly ejecting the water from said water-pipes, the combination, arrangement, and operation being substantially as shown and described.

G. The oil-conduit, with lateral horizontal pipes o, the cold-water pipe with lateral horizontal branches w, alternating with pipes o, as shown, and provided with the orifices .fr and y, respectively, the receiver D, the well or wells, with pipes for conveying` the water from the receiver to the wells, the pump P, with pipes communicating with said wells, all combined, constructed, arranged, and adapted to operate substantially as and for the purposes set forth.

In testimony whereof I have hereunto affixed I my signature this 20th day of March, A. D. 1883.
